Painting costs for a limousine – experiences?

Hello, I have asked in a workshop, the old cars (mostly MB) restored, for the estimated costs for a (complete) painting of my W202. The answer seemed quite high to me (would not want to blow out the exact span at first). They told me especially Metallic varnishes are more expensive. First of all: Yes, it would be wise to have an offer made by a paintmaker. Unfortunately, my car is currently not so 100% traffic-proof, so I don’t want to drive around unnecessarily. Especially because I almost assume that I will answer prices that will end my “project” finally. So:1) What would be appropriate in my case?Color: BRILLANTSILBER – METALLICLACK (744U)Quality: so good that the average person perceives it as a normal painting and does not identify it as a bad quality – but it doesn’t have to be absolutely perfect (hope you understand how I mean that).2) Have you had your oldtimer painted already and what it cost? Interestingly: Which color / how long is the cost?
